We now know that gravitational waves are real. Do they carry energy? I mean thy are waves and every wave carries energy.
If they carry energy, how do they do it?
Is there any equation to describe it?
Yes they do. They do this in the form of ripples. They distort the fabric of space time. They carry energy in the form of waves . Just like the type of distortion you can see in a
mat when you form waves in it.
However it ( mat ) has energy and you can see it.
Same in the case of gravitational waves , they carry energy in the form of ripples , or waves .
